Linux is just another OS. It&#39;s open source, though, and I believe you can get it for free (legally). It&#39;s usually used by the more technically minded person, not quite as user-friendly as the other OS out there. I haven&#39;t used the latest versions of Linux, so this could be completely inaccurate, and I honestly don&#39;t remember enough about it to make a decent comparision between it and XP.

things are quiet until hitler decides he'd like to invade russia
so, he does
the russians are like "OMG WTF D00DZ, STOP TKING"
and the germans are still like "omg ph34r n00bz"
the russians fall back, all the way to moscow
and then they all begin h4xing, which brings on the russian winter
the germans are like "wtf, h4x"
-- WW2 for the l33t
